Description

Medical enema system

Technical Field

The invention relates to the technical field of medical treatment, in particular to a medical enema system and a medical enema method.

Background

Enema is a therapeutic means in medicine, that is, a catheter is used to insert the colon from anus through rectum and perfuse liquid into intestinal tract, so as to achieve the effect of stimulating intestinal peristalsis or softening feces, and sometimes, the therapeutic effect can be achieved by a method of supplying medicines and nutrition.

Medical clysis means often require medical personnel to operate the clysis equipment to provide clysis therapy to the patient. Because medical staff can not sense the intestinal state of the patient himself, the enema process can be smoothly carried out by virtue of auxiliary detection equipment and the experience of the medical staff.

Chinese patent No. CN112755302B discloses an enema auxiliary device for gastrointestinal ostomy care, comprising a ostomy tube for extending into a gastrointestinal stoma; the enema tube is coaxially arranged in the ostomy tube and used for filling enema liquid into the intestinal body, and the enema tube and the ostomy tube can be arranged in a sliding manner; the auxiliary tube is coaxially arranged in the enema tube and is used for filling the cleaning liquid into the intestines; and the dredging component is used for dredging dirt between the ostomy tube and the enema tube, and a scraping rod is arranged in the dredging component and can scrape dirt attached to the inner wall of the ostomy tube, dirt on the outer wall of the enema tube and dirt blocked between the ostomy tube and the enema tube.

The most impediment to the enema process is the digesta in the patient's intestinal tract. Since many patients with enema need have a problem of difficult defecation, digesta in the intestinal tract of the patient can take a form of high hardness. When the enema liquid enters the intestinal tract, the high-hardness digesta can obstruct the flow of the enema liquid in the intestinal tract. If the pressure is increased, the enema liquid is filled into the intestinal canal, so that the peristaltic motion of the intestinal canal is accelerated, and the illusion of the excretion requirement is generated for a patient, and the intestinal mucosa is damaged. In the prior art, chinese patent No. CN101254321B discloses a system method for fully automatically pressing enema and cleaning vagina of human body and a sanitary machine thereof. The method for fully automatically pressing the enema and cleaning the vagina of the human body comprises the following steps: v is less than or equal to 13.82KP ₀ In the safe and effective pressure range of less than or equal to 29.23KP, the enema tube and the enema tube head which are suitable for the arc camber of the buttocks or the characteristics of the front pudendum and the anus of a human body are used for filling the temperature-suitable liquid with the temperature of 37+/-5 ℃ into the anus and the intestine of the human body to finish the enema or clean the pudendum; the sanitary machine comprises a liquid storage barrel at the uppermost end, a enema tube communicated with the liquid storage barrel is arranged below the liquid storage barrel, the enema tube is connected with a enema tube head, and the enema tube is provided with a enema tube head outlet which can keep the output of the enema tube head at 13.82KP less than or equal to V ₀ A pressure regulating device within a safe and effective pressure range of less than or equal to 29.23 KP. The patent provides an enema device that pressure value scope used safely, but the device does not carry out further refined management to the intestinal environment of patient's different state, along with the inflow of enema liquid, intestinal environment can change at any time, because artifical enema can't obtain further intestinal state change, consequently, the device also can't in time adjust the liquid velocity of flow who carries enema liquid to the intestinal. The incorrect flow rate of enema fluid generates pressure on the intestinal tract, on one hand, the enema fluid can not enter the intestinal tract any further; on the other hand, the pressure promotes intestinal peristalsis, so that a patient generates a excretion reaction under the condition that the intestinal tract is not fully infiltrated by enema liquid, and even the mucous membrane of the inner wall of the intestinal tract is damaged.

According to the invention, at least two detection methods are set based on the influence of the enema liquid on the intestinal environment when the enema liquid enters the intestinal tract, and the enema process of a patient is monitored in real time through the injection pressure of the enema liquid and the bowel sound of the intestinal tract, so that the speed of the enema liquid injected into the intestinal tract can be matched with the intestinal environment of the patient at any time.

Furthermore, there are differences in one aspect due to understanding to those skilled in the art; on the other hand, since the applicant has studied a lot of documents and patents while making the present invention, the text is not limited to details and contents of all but it is by no means the present invention does not have these prior art features, but the present invention has all the prior art features, and the applicant remains in the background art to which the right of the related prior art is added.

Disclosure of Invention

Enemas are generally classified into 3 types: a large amount of non-retention enema, a small amount of non-retention enema, and retention enema. A large number of non-retention enemas are commonly used to stimulate intestinal peristalsis, relieve constipation, remove intestinal flatulence, clean the intestinal tract and physically cool. The process of large scale non-retention enemas is generally a large dose which is slowly instilled into the anus and held in the intestine for a period of time after the fluid has been drained. The small amount of non-retention enema is generally used for softening stool, relieving constipation for patients with weak body such as pregnant women, old people and children, and removing intestinal gas for patients with intestinal flatulence after abdominal and pelvic surgery, so as to relieve abdominal distention. The procedure of the small amount of non-retention enema is similar to that of the large amount of non-retention enema, but the used enema liquid, the used amount of the enema liquid and the dropping speed are different from those of the large amount of non-retention enema. Retention enemas are generally used for the infusion of drugs, mainly sedative hypnotics and intestinal bactericides, into the rectum or colon where they are absorbed through the intestinal mucosa. The anal canal should be inserted deeper during retention enema, and the liquid should flow slower to reduce the pressure on the intestinal tract, thus being beneficial to the retention of the liquid medicine.

There are differences in the individual intestinal environments. There are different states of digesta in the intestinal tract. Bristol stool classification classifies digests in the intestinal tract into seven categories. The first type is sheep manure sphere, and the shape of the first type is like a single hard sphere; the second type is twist-shaped, and the surface of the second type is concave-convex; the third type is sausage-shaped, and has cracks on the surface; the fourth type is banana-shaped, and the surface of the fourth type is smooth; the fifth type is cotton candy, which is in a soft block shape with smooth broken edges; the sixth type is soft and thick, and is thick and fluffy, and is pasty stool; the seventh type is liquid or water, and has no solid block.

Digests of different morphology have different shapes and hardness. During the enema, when the enema liquid encounters too hard digesta, the pressure of the irrigation will change. For patients in need of enema, the intestinal environment is different due to different requirements. For example, for constipation sufferers, there is a high likelihood of having a high hardness and low penetration of digesta in the intestine, which type of digesta can affect the further flow of enema fluid into the interior of the intestine. For patients who need to be treated by the intestinal absorption of drugs, the internal environment of the intestine is healthy, and therefore, the probability of encountering digesta with high hardness and low infiltration when the liquid is infused is relatively low.

The rate of irrigation of the enema fluid needs to be varied in the face of different intestinal environments. Meanwhile, the hardness of digesta in the intestinal tract is not always kept unchanged along with the entry of the enema into the intestinal tract. Generally, the ingress of enema reduces the hardness of the digesta. Based on the environment which may change in the intestinal tract at any time, the inflow rate of the enema liquid also needs to be changed along with the environment change. By adjusting the speed of the enema liquid in real time, on one hand, the efficiency of the enema liquid flowing into the intestinal tract and lubricating the intestinal tract and digesta can be increased; on the other hand, the pressure which is caused to the intestinal tract by the excessively high flow rate at the unsuitable node and possibly damages the inner wall of the intestinal tract can be avoided.

Aiming at the defects of the prior art, the invention provides a medical enema system. The system comprises a detection unit for monitoring the rectal environment of a patient, a processing unit and a functional unit for injecting liquid into the rectum of the patient, wherein the detection unit comprises a first detection component for detecting the pressure of the injection of the enema liquid into the intestinal tract, and the functional unit is provided with a first regulating component for regulating the height of the enema liquid and a second regulating component for controlling the injection mode of the enema liquid into the intestinal tract of the patient.

When the detection unit detects that the functional unit is converted from a non-pressure environment into a pressure environment, the processing unit controls the functional unit to implement a first mode of enabling the enema liquid and anus of a patient to form a first height difference, and responds to detection data of the first pressure formed by the injection component of the digestive matters in the intestinal canal provided by the first detection component to the functional unit, the processing unit controls the functional unit to adjust from the first mode to the second mode, wherein the liquid injection flow rate of the functional unit in the first mode is a first set value, the liquid injection flow rate of the functional unit in the second mode is a second set value, and the first set value is larger than the second set value. The first height difference is used to increase the pressure between the intestinal tract and the enema liquid so that the enema liquid can enter the intestinal tract based on gravity.

The spray assembly in the first mode is capable of providing enema fluid into the intestine at the normal flow rates of enema fluid proposed in the prior art. However, during actual operation, the patient needs an enema due to abnormal environment in the intestinal canal, and the intestinal canal of the patient often blocks a large amount of digesta in abnormal state, and the digesta also block enema from entering the intestinal canal. However, the medical staff cannot visually and intuitively know the position change of digestant in the intestinal tract and whether the digestant affects the flow of the enema liquid, so that the pressure value of the enema liquid in the intestinal tract and the borborygmus feedback of the enema liquid in the intestinal tract are judged, and the flow rate of the enema liquid in the intestinal tract is adjusted in time. When the digestive matter is found to obstruct the flow of the enema based on the judgment of the two detection means, the system can be automatically switched to the second mode, and the second mode can adjust the flow rate of the enema in real time based on the detection result, so that the phenomenon that the flow rate is too high to cause the intestinal tract to produce an antagonism effect on the intestinal tract and cause an uncomfortable reaction on the intestinal tract is prevented. The digestive matter which prevents the entry of the enema liquid in the intestinal tract is faced, the speed of the inflow of the enema liquid is reduced, and the digestive matter is decomposed or softened through the infiltration of the enema liquid to the digestive matter, so that the digestive matter does not prevent the entry of the enema liquid. Meanwhile, the system can also confirm that the change of the currently monitored pressure value is caused by the physical form change of digesta based on the peristaltic frequency of intestinal tract found by borborygmus, thereby distinguishing the reason of obstructing the entry of enema into the intestinal tract. The second mode is: when the digesta obstruct the enema from entering the intestine, the enema decreases the flow rate based on the increase of the pressure value to prevent the stress reaction of the intestine.

The method for detecting the injection pressure of the enema liquid is used for monitoring whether digestate which hinders the inflow of the enema liquid exists in the current intestinal tract environment in real time. Specifically, when the injection pressure increases, it is indicated that there is a digest that impedes the flow of the enema liquid as it flows into the intestine. In the prior art, medical staff needs to hold an enema device and observe the enema progress in real time, and when the speed of enema liquid is found to be reduced, the direction of an anal canal in the intestinal tract of a patient is adjusted so as to enable the enema liquid to recover to the previous inflow speed. The method has hysteresis. Since the flow rate of enema is low and generally enters the inside of the patient's intestinal tract from the anal canal through the infusion bag, it is difficult for medical staff to find it at the beginning of the decrease in enema rate. The invention confirms whether digestate which obstructs the flow of the enema liquid exists or not through the flow pressure of the enema liquid. When an increase in pressure is found, it is indicated that a hard digest is present in the intestine, which plugs in the intestine and has a low infiltration capacity of the enema. The invention can automatically adjust the inflow speed or the injection speed of the enema liquid based on the pressure change. The influence of the enema on the intestinal tract of the patient when the digestant is received is reduced by timely adjusting the flow rate of the enema, so that the process of pouring the enema is always in the change of the flow rate which is not perceived by the patient, namely the pouring speed of the enema can not influence the sensory flow rate change of the patient on the intestinal tract. The sensory effect of the patient accelerates the intestinal peristalsis of the patient, which causes the patient to generate true/false excretory impulses, and the intestinal peristalsis is opposite to the inflow direction of the enema liquid to block the inflow of the enema liquid, so that the enema process is stopped. The influence of the sense of the patient can also promote the contraction of intestinal muscle, the contracted intestinal canal can lead the anal canal inserted into the intestinal canal to generate displacement of unpredictable movement positions, and the anal canal can be seriously removed from the intestinal canal, so that the problem of clysis failure is caused.

According to a preferred embodiment, the processing unit controls the functional unit to adjust from the second mode to the first mode based on a second pressure in the intestine provided by the first detection assembly, wherein the first pressure is higher than the second pressure. When digesta in the intestinal tract is gradually softened by the enema liquid, the digesta can not block the enema liquid from entering the intestinal tract, and the enema device can adjust the flow speed of the enema liquid back to the filling speed of the enema liquid in the first mode. The method can ensure that the enema device can normally perform the filling of enema liquid after the abnormal factors are solved.

According to a preferred embodiment, the detection unit further comprises a second detection component for detecting a patient's borborygmus, wherein the second mode comprises the following two processes when the first detection component detects that a first pressure is established in the intestine to the jetting component of the functional unit:

the processing unit controls the liquid spraying flow rate of the functional unit to a second set value; the processing unit controls the liquid injection flow rate at a second set value to be increased based on the increase of the data related to the borborygmus provided by the second detection assembly.

When encountering high hardness digesta, the liquid injection flow rate of the functional unit is first adjusted to the lowest flow rate for the primary purpose of reducing the pressure in the intestine. With the infiltration of the enema, the high hardness digestate is gradually changed and the hardness is gradually lowered. With the form of digesta gradually tending to not affect the form of irrigation of the enema, the liquid injection flow rate of the functional unit can be gradually increased without increasing the pressure in the intestinal tract.

Meanwhile, in order to distinguish the reasons for obstructing the entry of the enema liquid into the intestinal tract, the invention is provided with a detection unit for borborygmus. When the enema liquid has a function of lubricating and softening digesta in the intestinal tract, the borborygmus of the patient may exhibit a higher borygmus than before the enema, and the borygmus may be more loud and occur more frequently. When the enema enters the intestinal tract and softens digesta in the intestinal tract, the patient's borborygmus will change more significantly than before with the onset of the enema.

When the intestinal canal peristalsis, the intestinal lumen gas and liquid flow along with it, creating an intermittent air-over-water sound (or gurgling sound), known as borygmus. Normally, the borborygmus occurs regularly, 4 to 5 times per minute. All the abdomen was audible. For patients with constipation or intestinal obstruction, the frequency of borborygmus is reduced. When the enema is injected into the intestinal tract, the frequency of the intestinal borborygmus of the patient gradually enters the normal and even active frequency range due to the injection of the exogenous liquid and the gradual decomposition of the digesta.

During an enema, inflow of enema liquid is pressurized by the environment in the intestine, and in particular, the enema liquid needs to enter the intestine at different flow rates due to individual differences in the state and volume of digesta in the intestine. However, when the enema enters the intestinal tract, the enema softens the digesta, causing a change in the environment within the intestinal tract. Along with the gradual entry of enema into the intestinal tract, digesta in the intestinal tract can soften, decompose and even be diluted, and the pressure of the enema entering the intestinal tract can gradually decrease at the moment. In the prior art, a manual monitoring method is often relied on to adjust the injection speed of enema liquid. The injection of the enema liquid can influence the state of digesta in the intestinal tract, and the state change of the digesta can influence the injection pressure of the enema liquid to change the injection speed of the enema liquid, so that the change of the state of the digesta is indirectly determined through the change of borborygmus, and the injection speed of the enema liquid is timely adjusted.

When the system enters a second mode, the second detection assembly is started to work. The spray assembly injects enema into the intestine at a minimum flow rate. With the increase of the time for the enema liquid to enter the intestinal tract, the sufficient enema liquid infiltrates the digesta, so that the digesta are softened and decomposed, and the occurrence frequency of the intestinal borborygmus is gradually increased. With increasing bowel sound frequency, the spray assembly gradually increases the flow rate of the enema fluid. Preferably, the minimum flow rate can be 10ml/min.

The second detection component detects the volume of patient borborygmus. The processing unit records the occurrence times, time and volume of the borborygmus to count the occurrence frequency and volume change of the borygmus.

The processing unit is capable of generating a development function related to the number of occurrences or volume of borborygmus and increasing the rate of injection of enema fluid based on an increase in the slope of the development function. When the processing unit controls the injection assembly to increase the injection speed of the enema liquid, the first detection assembly detects the pressure of the intestinal tract on the injection assembly after the injection speed is increased. When the pressure does not exceed the first pressure, the processing unit can increase the injection speed of the enema liquid in a gradient way based on the increase of the slope of the development function related to the occurrence times of the borborygmus, so that the enema liquid can generate a scouring effect on the inner wall of the intestinal tract based on the inflow process and cannot hurt the intestinal environment due to the too high flow rate. Preferably, the rate of infusion of the enema fluid can be varied in a gradient, i.e. every 0.1 increase in slope, the rate of infusion of the enema fluid increases by 10ml/min. According to a preferred embodiment, the borborygmus is used to sense the peristaltic frequency of the intestinal tract. The frequency of occurrence, volume level, and sound type of borborygmus can be used to determine the current intestinal environment.

When the digestive matter in the intestinal tract is hard and aggregates into a block shape which blocks the intestinal tract, the sound produced by the flow of the enema liquid into the intestinal tract is mostly a waterflow sound. When the digesta in the intestinal tract is gradually softened, the enema liquid can be fused with more gas to form bubble sounds similar to gurgling, and when the digesta in the intestinal tract is softened or even disintegrated, the quantity of the bubble sounds emitted at the same time is increased, because tiny gaps which can allow the enema liquid to flow are generated inside the digesta in a pasty or dispersed state, and the increase of the flow paths of the enema liquid enables the enema liquid to form more bubble sounds in the intestinal tract. Therefore, by discriminating the sound type of the borborygmus, the state of the digestive tract can be discriminated. When the state of the digesta gradually enters a soft lump or paste shape which allows more enema liquid to enter the intestinal tract, the inflow speed of the enema liquid is tendedly increased without hurting the intestinal tract.

According to a preferred embodiment, the second detection assembly collects at least two varying factors of the borborygmus sound, the varying factors including the volume of the borygmus sound and the frequency of the borygmus sound. Preferably, the change in volume and frequency of occurrence of the current borborygmus is mainly referred to the volume and frequency of occurrence of the last borygmus.

According to a preferred embodiment, the functional unit comprises an anal canal and a jet assembly in communication with the anal canal, wherein at least one pressure sensor is arranged on the surface of the anal canal in contact with the intestinal tract, such that the detection unit is capable of providing the processing unit with data related to pressure changes of the environment in which the functional unit is located based on pressure data provided by the pressure sensor. The anal canal confirms whether the functional unit completely enters the intestinal canal of the patient by sensing the pressure difference between the inner and the outer of the intestinal canal, and the data difference is used as the basis for the processing unit to start the detection unit.

According to a preferred embodiment, the injection assembly is provided with a central injection hole, wherein the functional unit in the first mode injects liquid of a central single flow channel with a flow rate at a first set value from the injection assembly provided at the front end of the anal canal into the intestine. When the intestinal environment of a patient is healthy, the process of transporting enema to the intestinal tract can be completed through the middle jet hole.

According to a preferred embodiment, the injection assembly is provided with at least one side injection hole circumferentially distributed in the lateral direction of the injection assembly, wherein the functional unit in the second mode injects liquid containing at least an intermediate single flow channel and a lateral flow channel with a flow rate at a second set value into the intestinal tract from the injection assembly arranged at the front end of the anal canal, wherein the flow rate of the intermediate single flow channel is lower than the flow rate of the lateral flow channel. Preferably, the diameter of the middle injection hole is larger than that of the side injection hole. When high-hardness digesta exist in the intestinal tract of a patient, the digesta and the intestinal tract flow in a small quantity and low speed mode through the side jet hole which is arranged in the lateral direction, so that the contact between the enema liquid and the digesta is increased, and the efficiency of the enema liquid for softening the digesta is improved.

According to a preferred embodiment, the second detection component is a wearable sound sensing component with a man-machine interaction function.

According to a preferred embodiment, the second set point can be 0. When the pressure reaches the range of the first pressure, it is indicated that a high hardness digest or foreign matter is present within the intestinal environment. Since the digest or foreign matter cannot be directly detected for hardness, the flow rate of the modified enema liquid cannot be determined. In order to avoid the pressure of negative feedback generated by the set flow rate to the intestinal tract, the inflow of the enema liquid is stopped firstly (namely, the inflow speed is 0), and then the inflow speed is gradually increased along with the borygmus and the jet pressure, so that the inflow speed can be matched with the digest softened in real time.

According to a preferred embodiment, the anal canal is provided with a speed control assembly for controlling the outflow of liquid. The speed control assembly can open or close the anal canal and control the speed of the liquid flow in the anal canal.

According to a preferred embodiment, an acid-base test card is arranged in the holding bag for holding enema liquid and is used for measuring the pH value of the enema liquid placed in the holding bag.

According to a preferred embodiment, the outer surface of the containment bag is provided with graduations for measuring the volume of enema fluid.

According to a preferred embodiment, the side of the receiving bag close to the anal canal is provided with a rigid shoe. The collet is sleeved on one side of the accommodating bag. Medical staff can hold the collet and carry and hold the bag, prevent that the hand from forcing out enema.

According to a preferred embodiment, the middle of the outer side of the containing bag is provided with a back adhesive, and the back adhesive is used for adhering the containing bag to a wall body or an instrument, so that the containing bag is placed conveniently.

The invention relates to a medical clysis method. The method comprises the following steps:

inserting means for injecting enema fluid into the intestine;

based on the pressure difference between the inner intestinal canal and the outer intestinal canal, the device provides the enema liquid with the injection flow rate being a first set value to the inner intestinal canal;

when the lavage fluid encounters a digest of the first type or the second type in the intestine, the device increases the jet flow rate of the lavage fluid to a second set point based on the increased pressure of the fluid flow due to the hardness change,

wherein the first set point is greater than the second set point.

The present invention provides a system and method for large-dose enema.

The patient was 41 years old and constipation was 5 days old.

The liquid for large-dose enema generally uses normal saline or 0.1% -0.2% of soap solution.

400ml of physiological saline was placed in the infusion bag, which was about 50cm above the anus of the patient.

The infusion tube is connected with the anal canal 410, and the injection assembly 420 and the anal canal 410 are inserted into the anus to a depth of about 7 cm-10 cm after being lubricated. The anal canal 410 senses the pressure difference, and the processing unit 300 triggers the first detecting assembly 100 and the second detecting assembly 200 to operate. In response to the first pressure of 19KP provided by the first detection unit 100 to the injector unit 420 of the functional unit 400, the processing unit 300 controls the functional unit 400 to switch from a single intermediate flow channel with a flow rate of 30ml/min to a dual flow channel with a flow rate of 10 ml/min.

With the gradual inflow of enema, the patient's borborygmus did not change significantly. Based on the second pressure in the intestine provided by the first detection assembly 100, which forms 14KP for the functional unit 400, the processing unit 300 controls the functional unit 400 to adjust from the second mode to the first mode.

Then slowly dripping the enema. After the enema is completely dripped, the functional unit 400 is pulled out. The patient lies on his/her back and has control over the anal sphincter and remains there for 5 minutes to 10 minutes before discharging.

Example 2

Retention enemas are generally used for the infusion of drugs, mainly sedative hypnotics and intestinal bactericides, into the rectum or colon where they are absorbed through the intestinal mucosa.

The anal canal 410 is inserted 12cm into the anus during clysis. The minimum speed at which the liquid medicine is infused into the intestinal tract can be 5ml/min. The buttocks of the patient are lifted by 10cm, and the body position is favorable for retaining the liquid medicine.

Specifically, in response to the first pressure of 15KP provided by the first detection unit 100 to the injection unit 420 of the functional unit 400, the processing unit 300 controls the functional unit 400 to switch from a single intermediate flow path with a flow rate of 10ml/min to a single flow path with a flow rate of 5ml/min. At this time, the second detection assembly is started to work.

With the liquid medicine at 30 ℃ gradually entering the intestinal canal, digesta in the intestinal canal gradually soften and the resistance to the liquid medicine entering is reduced. The number and volume of occurrences of borborygmus in the patient vary.

The second detection component detects the volume of patient borborygmus. The processing unit records the occurrence times, time and volume of the borborygmus to count the occurrence frequency and volume change of the borygmus. The processing unit receives the data provided by the second detection component. The processing unit confirms the frequency of occurrence of the borborygmus.

With increasing bowel sound frequency, the spray assembly gradually increases the flow rate of the enema fluid.

The processing unit is capable of generating a development function related to the number of occurrences or volume of borborygmus and increasing the rate of injection of enema fluid based on an increase in the slope of the development function. When the processing unit controls the injection assembly to increase the injection speed of the enema liquid, the first detection assembly detects the pressure of the intestinal tract on the injection assembly after the injection speed is increased.

When the pressure is not higher than 15KP, the processing unit can increase the injection speed of the enema liquid in a gradient way based on the increase of the slope of the development function related to the occurrence times of the borborygmus, so that the enema liquid can generate a scouring effect on the inner wall of the intestinal tract based on the inflow process and cannot hurt the intestinal environment due to the too high flow rate.

Specifically, the injection rate of the drug solution was increased by 5ml/min every 0.1 increase in the occurrence frequency of borborygmus. The processing unit monitors that the occurrence frequency of the borborygmus increases by 0.1, and the processing unit controls the injection assembly to increase the liquid medicine injection speed by 2 ml/min. When the injection assembly singly increases the injection speed of the liquid medicine, the first detection assembly can detect the current injection pressure, and when the injection pressure is lower than 15KP, the second detection assembly can continuously detect and transmit the occurrence frequency of the borborygmus.

When the injection pressure is higher than 15KP, the processing unit controls the speed of the injection assembly to decrease by 5ml/min and detects the injection pressure again, detecting the injection pressure every 5ml/min as one step until, for example, the pressure is lower than 15KP.

Example 3

The present invention provides a system and method for small, non-retention enemas.

The patient was 12 years old and constipation was 5 days old.

The liquid for large-dose enema is generally glycerol plus an equal amount of physiological saline. The liquid temperature should be 39-41 ℃.

100ml of physiological saline was placed in the infusion bag, which was about 50cm above the anus of the patient.

The infusion tube is connected with the anal canal 410, and the injection assembly 420 and the anal canal 410 are inserted into the anus by about 6 cm-8 cm after lubrication. The anal canal 410 senses the pressure difference and the processing unit 300 triggers the first detecting assembly 100 and the second monitoring unit to operate. In response to the first pressure of 19KP provided by the first detection unit 100 to the injector unit 420 of the functional unit 400, the processing unit 300 controls the functional unit 400 to switch from a single intermediate flow path with a flow rate of 15ml/min to a dual flow path with a flow rate of 8 ml/min.

Example 4

The invention relates to an automatic pulse lavage system.

The system comprises a flow guiding pipe. The two ends of the flow guide pipe are respectively provided with pluggable interfaces at the near end and the far end through valves regulated by the system. The wall of the flow guide pipe is provided with side through holes which are spirally arranged, and the pluggable interface at the near end is connected with an elastic balloon in series. The elastic balloon can give negative pressure to the guide tube based on control of the system, so that enema liquid in the guide tube can enter the intestinal tract with different intensities (flow rates) and frequencies.

The pressureless environment means that digesta in the intestine do not cause an obstruction to the flow of enema liquid into the intestine. The pressure environment means that digesta in the intestinal tract cause an obstruction to the flow of enema liquid into the intestinal tract. The judgment of the non-pressure environment and the pressure environment is based on the pressure monitoring of the injection enema liquid.

When the detection unit detects that the functional unit 400 is converted from a non-pressure environment to a pressure environment, the processing unit 300 controls the pulse parameters of the functional unit 400 so that the enema can flow into the intestinal tract with the lowest pulse parameters.

Based on the change in the environment, the processing unit 300 triggers the second detection component to monitor the change in the environment within the intestinal tract. The second detection component can be an acoustic sensor and monitor the patient's borborygmus. The first detection component detects the pressure generated by the digest against the injection component 420 as the frequency of pulses of the enema increases by 0.1 for each 0.1 increase in the frequency of occurrence of the borborygmus, and as the frequency of pulses of the enema changes. When the pressure exceeds the first set point, the pulse frequency of the enema liquid is returned to 0.1, and the first detecting component detects again the pressure generated by the digesta to the spraying component 420 until the pressure is lower than the first set point.

According to a preferred embodiment, the processing unit 300 directs the functional unit 400 to provide the enema pulse mode of the low speed mode based on the pressure being less than the fourth set value in case the occurrence frequency of the borborygmus is greater than the third set value. The functional unit 400 in the low-speed mode can provide an enema injection mode with a pulse frequency of less than 10 times/min and a flow rate of less than 10 ml/min. The functional unit 400 for supplying the enema liquid into the intestinal tract at a low frequency and a low flow rate can prevent the illusion of excretion caused by the impact force of the enema liquid on the intestinal tract in an active state while ensuring that the digesta deep in the intestinal tract is infiltrated. Preferably, the third set point is not more than 2 times/s. The fourth set value is not greater than 10KP.

According to a preferred embodiment, the processing unit 300 directs the functional unit 400 to provide the enema pulse mode of the high speed mode based on the pressure being less than the fourth set value in the case where the occurrence frequency of the borborygmus is less than the third set value. The functional unit 400 in the high-speed mode can provide an enema injection mode with a pulse frequency of more than 20 times/min and a flow rate of more than 10 ml/min. A low frequency of borborygmus represents a low activity of intestinal peristalsis, meaning that even if the external lavage fluid is received, the intestine is still obstructed by a shaped and firm digestive mass and is not unobstructed, and thus the functional unit 400 can continuously provide a high speed mode of lavage fluid pulse mode. On one hand, the enema liquid in the mode can fully wrap digesta in intestinal tracts so as to achieve the aim of softening the digesta; on the other hand, the pulse frequency is high enough to increase the impact force of the enema and shorten the time for decomposing the enema and softening the digestate.

According to a preferred embodiment, the pulse frequency of the functional unit 400 can be gradually increased based on the decrease in the occurrence frequency of the borborygmus when the pressure is continuously smaller than the fourth set value. Based on the detection of the intestinal environment, particularly the effect of the digesta in the intestine (borborygmus) and the effect of the digesta on the jet assembly 420 (pressure), the system can change the pulse frequency and flow rate of the enema liquid in real time, so as to achieve the purposes of softening the digesta by infiltrating the digesta and providing an access channel for the enema liquid after the digesta are decomposed. The system can not damage the inner wall of the intestinal canal of a patient in actual use, and can not cause severe peristalsis of the intestinal canal to cause excretion reaction, thereby stopping the enema process.

The outer shell 550 wraps up not more than half of the volume of the enema storage bag 500, on one hand, can provide an operation area for medical staff to hold the enema storage bag 500 in the hands; on the other hand, the unwrapped location of the enema pouch 500 can be used to provide an indication of an enema to a healthcare worker.

Suspension assembly 510 includes a backing adhesive 512 and a suspension loop 511. The back adhesive 512 is disposed on the surface of the enema bag 500, opposite to the acid-base detecting component 530 and the temperature detecting component 540. The acid-base detection assembly 530 and the temperature detection assembly 540 are disposed on the same side. Preferably, the temperature detecting unit 540 is vertically disposed to cover each height position of the enema storage bag 500 in the filling direction of the enema, so that the temperature detecting unit 540 can achieve the temperature detecting effect when facing the enema storage bags 500 storing different volumes of enema. The length of the acid-base detection component 530 can enable the acid-base detection component 530 to extend into the bottom of the enema storage bag 500. Preferably, the acid-base detection assembly 530 is a pH paper having a length of at least greater than 15 cm. The acid-base detection assembly 530 can be immersed in enema fluid disposed at the bottom of the enema fluid storage bag 500.

The back adhesive 512 is a traceless adhesive for fixing the enema storage bag 500 to a wall surface.

The suspension loop 511 is provided at one side of the casing 550 which is sleeved with respect to the enema storage bag 500, as shown in fig. 3. Since a part of the clysis process requires adjustment of the height of the clysis liquid storage bag 500 with respect to the patient, the clysis liquid storage bag 500 is hung on shelves of different heights by the hanging ring 511, so that the medical staff can keep the clysis liquid storage bag 500 at different heights based on actual demands.

The enema fluid storage bag 500 is connected to the infusion tube 600, and the infusion tube 600 is connected to the injector assembly 420.

When the system is in a manual mode, the system does not work any more, and the flow rate of the enema liquid is regulated and adjusted only by the external regulation and control of medical staff. When the system is in the automatic mode, the system is turned on for operation.

The acid-base detection assembly 530 can be a PH paper. As shown in fig. 3, the PH paper can contact the enema from the opening of the enema storage bag 500 to monitor the PH of the enema.

Since the temperature of the enema liquid needs to be controlled at 38-42 ℃, a temperature detecting component 540 is arranged on the surface of the enema liquid storage bag 500.
